1.2Controls Overview

Miele dishwashers are currently categorized into three (3) product series, based on the type of controls.

Novotronic

Each Novotronic model dishwasher can be operated with a single knob. Surface mounted design technology (SMD) allows Miele Novotronic components to be extremely durable and reliable. These controls are capable of performing hundreds of tasks which cannot be handled by mechanical components.

Touchtronic

This new series of Miele dishwashers is operated by pushing a single button -- no separate temperature or drying selections -- just turn the machine on, pick a program and Miele does the rest. All models now include a Pots and Pans program and a Water Management System, designed to maximize cleaning results and optimize water and energy conservation.

3.4Water Softener

If your tap water hardness is above 8 grains per gallon (140 ppm), the water should be softened.

A Water Hardness Test Strip is used to determine the water hardness.

If the Water Softener is needed:

The dishwasher must be programmed to “with Water Softener” (ON).

The Water Softener reservoir is filled with softener salt.

The water hardness level is programmed into the dishwasher electronic.

If the Water Softener is not needed:

The dishwasher must be programmed to “without Water Softener” (OFF); however the hardness level is not programmed into the electronic

Salt is not needed and should not be installed.

Water Softener Salt

Only use water softener salt specially formulated for dishwashers.

Other salts may contain insoluble additives that impair the Water

Softener. The proper salt can be purchased from the Miele Technical

Service Department.

To add salt:

1.Remove the Lower Basket.

2.Unscrew and remove the Salt Reservoir Cap located on the floor of the Wash Cabinet.

3.If this is the first time salt is installed; add 2 quarts water.

4.Place a funnel over the Salt Reservoir. Carefully fill with salt.

4.0Description of Function

4.1Cabinet Construction

The inner cabinet is constructed of stainless steel (1.4301) welded onto four (4) vertical U-section sub-frames. The cabinet is sound and heat-insulated with bitumen and/or mineral wool matting.

4.2Fan Assembly

(Units equipped with Turbothermic Fan)

The fan assembly consists of the Fan Motor (M2) and a PTC Release

Element (Y56), which opens the air outlet flap. The 120VAC fan operates in the drying stage, after a brief delay. The PTC Release Element is activated, and the Air Outlet Flap is partially opened. A bypass channel behind the air outlet is also opened and ensures that the moist air from the cabinet is mixed with dry air from the door interior. This measure prevents condensation from developing. After about a minute, the electronic switches off the Release Element, however the Air Outlet Flap remains partially open. After a few minutes the Release Element is activated again, which completely opens the

Air Outlet Flap. The fan operates constantly throughout this period until the program ends.. The Air Outlet Flap remains open at program end and closes when the dishwasher door is opened.

4.2.1PTC Release Element

(Units equipped with Turbothermic Fan)

When 120VAC is applied to the Release Element, the PTC Resistor heats a small grease-filled capsule. As the grease expands it pushes a piston upward and slides the Air Outlet Flap to a partially open position. When the Release Element is activated the second time, the piston slides the Air Outlet Flap to a fully open position.

4.3Combination Dispenser

4.3.1Construction

Two individual solenoids control detergent and rinse aid dispensing.

The Rinse Aid Reservoir has a capacity of about 130 ml. When the

Rinse Aid level drops to about 25 ml. the Magnetic Float activates a Reed Switch on the edge of the dispenser and the Rinse Aid LED illuminates.

Technical Information

4.3.2Dispensing

During the main wash, the Detergent Solenoid (Y51) is energized (120VAC), to open the Detergent Dispenser Flap. The water jet from the Middle Spray Arm flushes detergent out of the dispenser.

Table 4-1: Detergent quantity in Combination Dispensers C2.06 and C2.09.

During the final rinse the Rinse Aid Solenoid (Y50) is energized (120VAC), to open the dispenser chamber and allow Rinse Aid to be dispensed into the cabinet.

Note

The Rinse Aid only flows from the reservoir into the dispenser chamber when the front door is fully opened at the end of a program.

The quantity taken into the dispenser chamber depends on the dispenser selector setting.

Table 4-2: Rinse Aid Dispensing (Combination Dispensers C2.06 and C2.09).

When the Rinse Aid Light turns on, an additional 2 to 5 dispensings (at setting 2) remain available.

Note

To allow proper filling of the Rinse Aid Dispenser; Rinse Aid should only be added with the door in the fully open position.

4.4Heaters

During the main wash and final rinse portions of a wash cycle, the water is heated to the programs specified temperature before advancing to the next step in the program (i.e.Thermal Stop).

The water is heated using one of two systems:

4.4.1Wash Cavity Heating Element

Figure 4-2: Cavity Style Heater Element

The Heating Element is mounted just off the floor of the wash cavity.

When powered (120 VAC) the element radiates heat thereby heating the surrounding and circulating water. The temperature of

the water is monitored by the Temperature Sensor, mounted in the Sump.

Heating Element switching is performed by the electronic via a Relay.

The relay (when energized) closes contacts to provide the Heater Element with 120VAC. A Temperature Limiter mounted with the element provides protection by opening up the circuit should the temperature become to high.

4.4.2Flow Through Heater:

The Flow Through Heater Assembly is mounted on the (left side) exterior of the wash cabinet. The Flow Through Heater is plumbed into the water path between the Circulation Pump Output and the Middle Spray Arm.

The Flow Through Heater Consist of a Heater Element mounted parallel to a metal tube that water passes through when the dishwasher is circulating.

As water flows through the metal tube; the water is heated and exits through the Middle Spray-Arm. As the water falls to the bottom of the wash cavity, it passes through the filter and re-enters the Circulation

Pump - the process then repeats.

The Temperature Sensor monitors the water temperature until the programs specified temperature is

reached. Generally the water heats Figure 4-3: Flow Through Heater about 20 per minute.

Heating Element switching is performed by the electronic via a Relay.

The relay (when energized) closes contacts to provide the Heater Element with 120VAC. Two Temperature Limiters are mounted along the element and provides protection by opening up the circuit should the temperature become to high.

4.6Pulsed Heating - Operation

In certain programs the heating may be operated at full power until a water temperature of 77°F is reached; then power is applied in pulses. This extends the heating time and allows enzyme-containing detergents to develop their full cleaning potential.

The pulsed heating operates as follows:

•1 min heater element on.

•1 min heater element off.

The number of pulse cycles is limited to a maximum of 11. If the programs specified temperature has not been reached, the heating resumes using full power. Once the programs temperature has been reached, the electronic unit advances to the next step in the program.

If the temperature cannot be reached (i.e. heater failure) within a specified time, the program will advance; and a heating fault is stored in the electronic.

4.7Temperature Protection

The Flow-through Heater uses two (2) Temperature Limiters (2F2) mounted on the body of the Flow-Through Heater. The Temperature Limiters are designed to open the circuit should the temperature become too high. When the temperature falls, the Temperature

Limiters do not reset automatically and must be reset manually (via the red button on the back of the device).

Additional protection is provided by the Electronic, which switches the appliance off and stores an F4 fault code, should the temperature exceed 194°F (90°C) – as determined by the Temperature Sensor.

4.8Static Drying

The Static Drying System uses no electrical and / or mechanical components to assist in drying. With this system the final rinse water is heated to 154°F (68°C) (not the usual 150°F / 67°C). The dishwasher cabinet is made of stainless steel; and conducts the heat generated during the final rinse. As the final rinse ends this stored thermal energy radiates and assists in the drying.
